Info

name     : doctrine/orm
versions : * dev-master, 2.6.x-dev

Reproduction

I have a schema which contains the following:

    /**
     * @ORM\ManyToOne(targetEntity="EntityAbc", inversedBy="children", cascade={"persist","remove"})
     * @ORM\JoinColumn(name="base", referencedColumnName="id", onDelete="SET NULL")
     **/
    private $base;

    /**
     * @ORM\OneToMany(targetEntity="EntityAbc", mappedBy="base")
     **/
    private $children;

I create a new EntityAbc. The children property is an empty collection now. For testing reasons I fetch the entity again from the repository, the children property is still empty as expected.
In the postUpdate/postPersist event the children property is also an empty collection as expected.
But when I delete the entity and the postRemove event is called, the children property contains a Doctrine\ORM\PersistentCollection which contains every EntityABC which is present in the whole table except the current one - so the children property contains now 199 entities when my EntityABC table have totally 200 entities

I use symfonys VarDumper to output the entity in the postRemove event.
